MG Part No: 839-900ML

The 839 Graphite Conductive Coating is an economical, acrylic paint that is used to create conductive, static free surfaces with excellent characteristics. Coated surfaces reduce electromagnetic or radio frequency interference (EMI/RFI). The graphite in the coat resists rubbing off to the touch. Further, the cured coat is designed to withstand large temperature changes without cracking.

  • High Conductivity—Low Surface resistivity of 47 Ω/sq for one coat (1 mil)
  • Tough and durable coating
  • Rub off resistant
  • Corrosion resistant coating
  • Stronger adhesion than water based coatings
  • Low VOC’s

Applications & Usages:
Its primary application is to provide low cost EMI/RFI shielding or conductive base for some electroplating process, or anywhere in a manufacturing process where it is necessary to impart conductivity to a surface. It works well on drywall, and can be used to shield entire rooms. For detailed instructions refer to the 839 TDS (Liquid).



Do not use on thin plastics or on plastics where you want to keep original surface intact. The 839 spray contains a controlled amount of solvents designed to chemically etch plastic surfaces to help adhesion by melding the acrylic coating into the plastic substrate. This prevents flaking or peeling. Using the 4351-1L thinner lessens the etching effects for chemically sensitive substrates.

Adhesion—The 839 coating adheres to most plastics used to house printed circuit assemblies; however, it is not compatible with contaminants like water, oil, and greasy flux residues that may affect adhesion. If contamination is present, clean the surface to be coated first.
